Wagstaff School is where Louise, Gene, and Tina go to school. The school is an old two-story brick building. It first appeared in the pilot episode, "Human Flesh" as a flashback. The school was the sole setting for Work Hard or Die Trying, Girl. It appears to include grades 1-8 (or possibly K-8), as all three Belcher kids wouldn't be in the same school otherwise.
In "Gene It On", the school's colors appear to be blue and white with a yellow W. In "Mazel Tina", Tammy appeared wearing a cheerleader uniform with a W on it (indicating Wagstaff), but the colors are white and red.
